title: Comparison of the effect of two heights of glycine irrigation solution on serum sodium and osmolality during transurethral resection of the prostate.
abstract: BACKGROUND
  The absorption of sodium-deficient, hypotonic irrigation solution is believed to contribute, in certain cases, to hyponatraemia and hypo-osmolality and, in severe cases, to the so-called transurethral resection of the prostate (TURP) syndrome.
  
  
  METHODS
  The effect of the height of 1.5% glycine irrigation solution during intermittent-flow TURP on serum sodium and osmolality was studied peri-operatively in 40 patients. The height of the glycine was set at 70 (n = 20) or 150 (n = 20) cm above the operating table.
  
  
  RESULTS
  We found no statistically significant difference in the measured serum sodium (P = 0.929) and osmolality (P = 0.260) values between the two groups during the 24 hr study period.
  
  
  CONCLUSIONS
  The height of the irrigation solution is not important in the development of hyponatraemia and hypo-osmolality, and other factors are probably more important.
